Mobile designers can go by many names, including app designers, iOS designers, Android designers, and more. They usually work closely with user experience (UX) designers and user interface (UI) designers to apply their designs to mobile interfaces. Their main focus is on native mobile applications, but they also must be able to create designs for mobile and hybrid apps.
Writing a good job description and a corresponding job ad requires a good understanding of different mobile design approaches, and it is necessary to carefully select skills and requirements that will filter out candidates unable to meet your expectations. A generic mobile developer job description will merely attract applications from people who are involved in mobile app development rather than design.
